spkBox: Fold Change Calculations

In spkTools: Methods for Spike-in Arrays

Description

A function to calculate the log-ratios stratified by which ALE groups yield the comparison. They are stratified by which bins are being compared to produce the given fold change.

Usage

spkBox(object, spkSlopeOut, fc = 2, tol = 3, reduce=TRUE)

Arguments

object	a SpikeInExpressionSet object
spkSlopeOut	the output of the spkSlope function
fc	the fold change of interest
tol	the precision (number of digits after decimal point) in fc
reduce	if TRUE the number of points plotted in the null bins is reduced

Details

This function requires the output of spkSlope.

Value

A list with the log-ratios separated by ALE strata comparison.
